Received my Dragon in September 2023. A member of AVS and the Facebook owners group, I've been working on tweaking and tuning this monster system for quite some time. Original released with Firmware 1.08, most of the issues with CEC, subs, HDMI have been fully resolved.
My equipment consists of an Nvidia Shield, Roku, Zidoo Z9X, fed directly into the Dragon using HDMI 2.1. The Dragon goes into a Lytmi Fantasy 3 backlighting box, and then EARC itno my Samsung QN85QN90B.
